SPECIFICATION forming part of Letters Patent No. 461,547, dated October 20, 51891. Application filed June 2, 1891. Serial No. 394,875. (No model.)

To a whom it may concern.-

Be it known that I, J on): W. SEIVERT, a citizen. of the United States, residing at Medical Lake, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Propelling-lli'heels;

and I do declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the'accompanying drawings, and to the letters of reference marked thereon, which form a part oft-his specification.

This invention relates to wheels for propellim vessels and water-crait, andirhich maybe used equally well in a-current for drivin machinery.

The object of my invention is the construction of a wheel in which the paddles will offer a minimum resistance to the water in entering and leaving the same, and which will perform ellicient work from the moment of entrance of the paddles into the water until they leave the same.

Another object of the invention is to hold the paddles in the relative iropcr position in a positive manner, and 0 provide means whereby the relative position or angle of the paddles may be changed, so that they may be caused to enter, pass through, and leave the water in a vertical or perpendicular position or at any required angle to the perpendicular.

The improvement consists of the novel features and the peculiar construction and combination of the parts, which will be hereinafter more fully described and claimed, and

which-arc shown in the annexed drawings, in

which Figure 1 is a perspective view of a propeller-wheel einbodyinir my invention. Fig. 2 is a cross-section of the wheel, taken at right angles to the axes of the paddles. Fig. 3 is a detail View of the plate fox-controlling the position of the paddles, the support for the said plate which is set eccontrically to the axis of the wheel, and the means for securing the said support in the located position.

The shaft A is provided near each end with arms B, between which the paddles C are supported in the usual manner, being provided with journals which have hearings in the said arms B. The journals of the paddles are pro-.

jected at one end beyond the arms B and ter-' minate in the cranks D, which have conuection with the plate F, that is mounted upon the support F, which is set eecentrically to the axis of the wheel. The support F is adjust-.

able to vary the position of the plate E relative to the arms B, thereby changing th irelative position of the paddles C.

p G is provided with an openingg sufficiently large-toreceive 'thethreaded stem e of the support F and a1:

The plate Ej is adapted to revolve freely on the supportEi and turns with the wheel in the operatio'nof the-invention The hearing I 5 low of a limited adjustmentof the samero' shift the position of the said support. The;

nut e on the stem e binds against the side'of" the bearing G and holds the support F in the located position.

The paddles present more surfaceon one;

side of their axes than 011 the other; This superior side will be referredjo as the wide side of the paddles.

The operation of the invention is as follows: The wheel is mounted in any suitable manner,

the frame [1 shown beingof ordinary form,

and the supportF and plate E being adjhsted to bring the paddles in a vertical position or at any required angle to the perpendicular.

The wheel being rotated, the plate E- is'caused to turn on the support, and through the cranks I.

D control and maintain the paddles in the proper position. When the wheel is used for propelling purposes, the wide side of the pad (US must be lowermost, and for motive power in a current of water-the wideside must be uppermost.

Having thus described my in vontion, what I claim to be new, and desire to secure by Let tors Patent, is

A wheel composed of a shaft, arms near each end ofsaid shalt, asupport F,plate I), mounted on said support, which is set eccentrically to the axis of the wheel, said plate adapted to revolve freely on the support, the cranks on ter forms a bearing for the shaft of the wheel, the journals of the paddles connected with substantiallyasand for the purposedeseribed. 1o
